a case of the budd chiary syndrome (bcs) in a 43-yr-old man with hydatid cyst (hc) in the liver is reported from imam ali hospital, kermanshah, western iran in 2016. this case was complicated by inferior vena cava (ivc) thrombosis, right atrial clot and pulmonary emboli. compression of ivc was the likely mechanism. abdominal ultrasonography revealed a huge hc located in segments near ivc and ca...

BACKGROUND The effects of surgical pneumoperitoneum on lower-limb venous hemodynamics have already been studied; however, the effects of intermittent compression boots are not known in such venous-stasis conditions. METHODS In 12 volunteers and 12 patients, the venous hemodynamic effects of intermittent leg compression were studied under external abdominal pressure or during laparoscopic chol...

Abdominal pumping in caterpillars has only been documented during molting. Using synchrotron X-ray imaging in conjunction with high-speed flow-through respirometry, we show that Manduca sexta caterpillars cyclically contract their bodies in response to hypoxia, resulting in significant compressions of the tracheal system. Compression of tracheae induced by abdominal pumping drives external gas ...

The addition of IAC to otherwise standard CPR provides for the application of external pressure over the abdomen in counterpoint to the rhythm of chest compression. Interposed abdominal compression is a simple manual technique that can supplement the use of adrenergic drugs to increase both coronary perfusion pressure and total blood flow during CPR. Mechanistically, manual abdominal compressio...

A 50-year-old woman with end-stage renal disease secondary to autosomal dominant polycystic kidney disease was referred to a quaternary care center due to significantly increased abdominal girth. Her physical examination revealed tense ascites and abdominal collateral veins. A 10-L paracentesis improved abdominal discomfort and disclosed a transudate, suggestive of portal hypertension. A comput...

Hemobilia represents gastrointestinal bleeding that develops as a result of communication between blood vessels and the biliary tract, which causes the blood to reach the duodenal papilla. It is characterized by biliary colic as the initial symptom, and the complications of cholangitis, obstructive jaundice and/or anemia. In general, definitive diagnosis is made by esophagogastroduodenoscopy wh...

Median arcuate ligament syndrome is a rare disorder that is clinically characterized by the triad of postprandial abdominal pain, weight loss, and often an abdominal bruit due to compression of the celiac artery by the median arcuate ligament. Given the nonspecific symptoms, this is a rare and difficult diagnosis to obtain. We present a patient with nonspecific abdominal pain in whom etiology w...

Blunt abdominal aortic injury is an infrequent occurrence after blunt trauma. The majority of these injuries result from deceleration forces sustained in motor vehicle collisions. Effects of these forces on the thoracic aorta are well described, but associated spinal compression or distraction can also lead to injury of the affixed abdominal aorta. We present a case of multifocal blunt thoracic...

This report describes an 18-year-old woman presenting with abdominal distension, left flank pain, and hypertension. She had a huge abdominal mass, diagnosed as a mesenteric desmoid-type fibromatosis, causing compression of the left external iliac vessels and ureter, as well as elevated renin concentration and hypertension. After surgical removal of the mass, all signs improved including hyperte...
